Applicationjfiled September 6, 1910. Serial No. 580,680.

To all ui/1.0m t may concern Be it known that I, CLARA ELLEN VViLLs, asubject of the King of Great Britain, re siding at Southport,Lancashire, England, have invented certain new and useful Improvementsin Gas Cooking-Stoves, of which the following is a specification.

This invention relates to gas heated cooking stoves, and it has for its'object to more fully utilize the heat obtained therein so that theutmost economy in gas consumption is obtained with increased utility ofthe stove.

The stove is made with a box top or chamber above the oven, andvavithinsaid chamber one or-more gas rings or vjets are inclosed, the top plateof the chamber being heated thereby so as to enable cooking to be donethereon while the heat produced by the burning gas jets is also utilizedto heat a compartment in said chamber beneath the gas rings, and is alsoadapted to heat the water contained in a vessel arranged above andadjacent to the stove. Means arealso provided for conveying the wastehot gases .from the gas jets in the oven to the box to-p or chamber andto said water vessel for the purpose of heating the same.

rlhe invention also comprises means within the oven, for directing theheat to ,any part thereof andr to any, desired part or parts of theviands therein. Additional heating. space is also provided inconjunction with the water vessel for the purpose of utilizing the wastehot gases therefrom, and the steam generated in said water vessel may beconductedjto any desired cooking utensil. The invention also comprisescertain other improvements which will be hereinafter fully set forth.

In order that the invention may be more clearly understood, I havehereunto Aappended the accompanying sheets of draw ings, whereon:-

i41 igure 1 is a perspective view of my improved gas-heating cookingstove, the oven door and the front of the box top or chamber being shownopen and the interior plate or tray being shown partially drawn outwhile certain details are omitted for theysake of clearness. Fig. 2 is asectional elevation on the line X, X, Fig. 3, certain parts beingomitted or broken away for the sake of clearness. Big. 3 is a plan ofthe stove, 4various parts being removed or omitted in order to showclearly the pipe arrangement.

Fig. 4 is a sectional elevation, to an enlarged scale, on the line Y, Y,F ig. 1, the section being composite with regard to the tray 18 in orderto sho-W the grid 24 and certain pai'ts being omitted to avoidconfusion.

i Throughout the drawings the same reference numerals, whereverrepeated, indicate the same or similar parts.

The stove'shown on the drawings is made with a box top or hollow chamber1 arranged above the oven 2` and provided with an opening front 3 hingedat its lower edge at 4 tothe casing 5 of the stove, being supported,preferably, when open by means of quadrants or the like 6, so that thefro-nt 3, when open, as shown in Fig. 1 forms a convenient shelf infront of the stove, at they same time, permitting access to the interiorof the chamber 1. The hingedfront 3 may be retained in its closedposition by any suitable retaining means, such as the `turnbutton 21.@ne or more gas rings or jets 7 of usual construction are provided inthe chamber 1 beneath openings formed in a top plate 9 which, as will behereinafter explained, also acts as a hot plate., Suitable covers 10 areprovided for closing said openings When the latter are not `covered byacooking utensil. The gas is sujplied to the burners 7j inthe usualmanner y way of a pipe 11 and branches 12, a branch13 being ed to gasburners 14 in the lower part of the oven 2.A Air is supplied to thechamber 1 by way of passages 15 at the sides thereof, said passagesbeing open at the front and back of the sto-ve and communicating lwiththe chamber 1 by way of openings 16, (Figs. 2 and 4) in plates 17between said passages 15 and the chamber 1. Within the chamber 1 isslidably and removably fitted ay plate or tray 18 resting on brackets 19securedto the plates 17 said tray forming the top of a compartment 20,below the gas burners?, which may be used for heating cooking utensilsor for keeping viands and dishes warm. r1`he tray 18 also serves toprevent dust, dirt or fumes from the gas burners 7 from fouling thecompartment 20. The tray. 18 is lmade with a slidable or otherwiseremovable part 22 adapted to open or c lose an opening or cut-away part23 provided with a` grid 24, so that, when the tray 18 has been pushedin, the grid 24comes beneath a griller 25 (F ig. 8) connected Awith thepipe 11 by a. branch pipe andori uncovering the grid 24 by means of theremovable part 22, meats may be grilled thereon.

At vthe rear of the stove, and, preferably, supported thereon, is awater-heating vessel 26, preferably, made with an outer enameled ironcasing ylined with silicate cotton or other non-conducting material-27(see Figs. 2 and 4) and having therein a number of vertical heating-tubes 28 communicating at the top with a compartment 29"and at thebottom with 'a compartment 30 (see particularly Fig 4) hereinafterreferred to as a waste hot gas chaimber. This waste hot gas chamber 30'communicates by way of a flue 31 with the chamber 1, the passage of `thehot gases from the chamber 1 being cont-rolled by means of a slidingdamper 32 having a handle 32u by means of which it may be adjusted, saiddamper also enabling 34 for filling and an outlet pipe 35 leading 'intothe upperpart of the water vessel 26.

The: vessel 26 is provided with the usual draw-0E cock 36 and watergage'37,*iand with a -vent pipe 38 leading into-'the upper part of thereserve water chamber 33-'airid Ienabling air to escape'when thetank-2611s being filled, a steam pipe 39 being also led from the upperpart 'of the water vessel'26 to the exterior and provided with asuitable regulating cock 40 and connection 41`to i be connectedaflexible pipe f42 for conducting the steam to' any suitably placed steamcooking utensil. rlhe cooking utensil may be supported on a shelf 44(see Fig. 8) secured' to the side of the oven.

As shown at Figs.`1 and 4, l preferably arrange an additional heatingchamber. 45 in front of the water vessel 26 and suitably secure sametothe said vessel. The heating Chamber 45 is provided with 'a perforated'shelf 46 and communicating with the space between the said `shelfandthe bottom of` the chamber 45 i's a pipe-connection 48 for supplying hotgases from the upper coinpartment 29, hereinbefore referred to, said:gases entering the' space between the shelf 46 and the bottom of thechamber 45 by way of an inlet at one end of the said chamber andrisingthrough the perforations in the shelf 46 and passing out at the front ofthe heating chamber 45.

One or'more coils `of piping 52 may be' passed' around the gas rings '7'in theiehairn-v License i bei' 1, as shown clearly at 3, said pipingbeing 4connected the water vessel 26 s0l that water will circulatethrough said piping and, owing to the proximity of the coils y to thegas bui-ners, the water will be heated thereby. y

A flue 53, see Figs. 2 and 4, communicates with the oven 2 and with thechamberl so that, when the ovenburners 14 are lighted, the hot gasestherefrom pass up the lflue 53 and are utilized"`for heating the hotplate 9, the hot 'gases passing away from the chamber 1' in themanneralready described. The hot gases in the oven 2 are also utilized to heata coil of piping 55 in the upper part thereof, said piping 55' beingalso connected to and communicating with the water vessel 26 so thatwater willcirculate thro-ugh the piping and be heated therein.Similarly,

when the oven burners 14 are not lighted, the oven will be, more orless, heated by the hot water from the vessel 26 circulating in thepiping 55. v. 1 I

@ne of the chief advantages of this stove is .the small consumption ofgas, the burners being-inclosed andthe heating power of the gas used tothe fullest extent. v In the ordinary gas stovewith the openburners,when a pan or k tle,'etc., is placed over the burner, a largepercentage ofthe heat, together with the fumes, rise around the edges ofthe .utensil and pass into the room. With the improved stove, as madeunder my invention the gases, usually wasted, travel over the coilsof-the water-circulating pipey or pipes connected with the hotl watervessel,heating and causing the water therein to circulate andthusassisting'in the heating-'of the water in the vemel.- The hot Y gasesafter passing over the coils of piping travel under the top plate of thestove inaking itinto an leffective hot plate capable of being used forcooking. The gases then pass through the iue 3 1 and rise through thevertical tubes 28 in the watervessel, heating the water therein, the'liot. gases passing into the compartment 29 and under the reserve waterchamber or tank slightly heating the water therein. The hot gasesthereafter pass by way of the pipe connection 48 to the additionalheating chamber heating the shelf therein and passing from thence intothe atmosphere or being conducted to a chimney or other suitable outlet.

rlhe hot gasesfi'om' the burnersl in the oven are first utilized forheating or cooking meats therein, as will be hereinafter moreparticularly set forth, Vthereafter heating the pipe coil -55 and thenthey are led up the iue 53 into the chamber 1 where they are furtherutilized for heating the hot plate 9 and passing from the chamber l,enter the flue 31 and waste hot gas chamber 30 and passing therefrom',through the tubes 28, they heat the water in the vessel 26 and thenposite one another and just above'and in 'capable of moving through theare of a Lieto pass through thei chamber 29 below the reserve water tank83 and finally pass away as hereinbefore described.

rlhe interior o'f the oven 2 is provided with two reflectors or vanes 56arranged opproximity .to the gas jets 14, the delectors being hinged orotherwise jointed to the casing at 57 inside the oven 2 so as to becircle, 4each deflect-or 56 being adjustably supported in an inclinedposition by means of a notched `or toothed quadrant 58 arr'an'ged at oneend thereof, The deflectors are, preferably, perforated so as to enablepart of the hot gases from the gas jets 14 to pass through thedeflectors and to be distributed above the same.

Y- The arrangement is such that, if, for instance, `a joint of meat isto be roasted, the deflectors can be manipulated so as to direct the hotgases from the gas jets to precisely such part or parts of the joint asmay be desired. My invention also enables practically all the hot gasesto be effectively utilized for cooking the meat, and, consequently, lessgas is'required than at present and waste is avoided. x
